CAR-DOOR.

Patented July 15, l1913..

Application filed March 31, 1910. Serial No. 552,717.

To all/whom i may concern o Be it known that I, EDWARD PossoN, a citizen of the United States, residing at, Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Doors, of which the following is a specification.

The principal object of my invention is to provide a new and improved door for railway freight cars.

Another object of my invention is to provide a door for railway freight cars that shall be adapted to hold grain in the car.

Another object. of my invention is to provide a sheet metal outside door for freight cars. l

A further object of my invention is to provide a door that shall have some or all of the following characteristics; convenient to manipulate, secure when closed, simple and' inexpensive in construction, not liable to `get out of order.

My invention is defined in the appended claims. In the accompanying drawings I have shown one speeiic embodiment thereof which I now proceed to describe'in this specification. I

Figure 1 is a front elevation of the entire door. F ig. 1a is a vertical section of the entire door, taken on the line 2-2 of Fig. 1.

Fig. 2 is a section ofthe upper partof the door taken on the line 2,2 of Fig. 1. Fig. 3 is a. section on the saine line ot the intermediate part of the door. Fig. 4 is a section on the same line of the lower part of the door. Fig. 5 is a horizontal section on the line 5, 5 of Figi. Fig'. is a hmizontal section on the line G, 6 of Fig. 1. Fig. 'T' is a horizontal detail section on the lino "i", T of Fig. 1. Figs. 8 and 9 are vertical sections taken on the line 8, S) of Fig. 1." Fig. 10 is a detail elevation of one ofthe auXiliary doors. Fig. 11 is a top edge view of the same. Fig. 12 is an end view of the same, and Fig. 13 is a perspective View of a guide.

The side wall of the freight car has the sill 15, the side posts 16 and thetop fraaie member 17.

The door disclosed in the drawings is an outside door comprising two main sections, an upper section 18 and a lower section 19.

Attached to the top frame member 17 above the dooropening is the Z-bar 20,.having one flange lying against the car wall and the other flange hanging downward. This holds its vright-hand Z-bar affords a track and guide on which the top section 18 is hung. The top door section 18 is ot sheet metal with two parts 2S) at the upper corners struck out as shown in the drawings. To these struck out portions 2S) hangers 21 are attached by means of rivets and they engage the track 20. y

The upper door section 18 is shown in horizontal section in Fig. 6. y A t the right a vertical strip or cleat- 23, with out-turned edge, is secured to thedoor post 16 by means of Ibolts 211. The right-hand edge of the door section 18 is doubled over, as indicated by the reference numeral 25, and adapted to slip tightly under the lip 23. At. the lett-hand side, the door section 18 has riveted to its edge a hook-shaped strip 2T which, when the door Ais closed, engages the strip 26 fastened to the door post- 16 by means of bolts 28. Thus it will be vSeen'that when the door section 18 is closed'by moving it to the right, the lip 23 engages and edge 25 and Athestri 26 engages and holds the hooked left-hand edge 27. l

lThe lower door section 19 opens to the right, this direction being the opposite of that for the upper door section 18. The various coacting elements 23', 24', 25', 26 and 2T correspond, respectively, to the parts designate-d with the corresponc ing numerals in connection with the upper door sect-ion'18. The lower edgeof the upper door section is offset to' form a stiffening rib'l shown in Fig. '2. It is further strengthened by a metal bar 30. riveted adjacent to the oset 31 by means of the' rivets 32. The extreme edge of the. door section 18 is doubled, as

'indicated by the reference numeral 33.

Attached tothe side posts 16 are guide blocks 3,4,"each having a T-'head 35, and secured in place by means of bolts 36. The T- heads 35 enter the pocket 31 on the lower edge of the upper door section 18 agidhook under the metal bar 30. Thus the. Thead carry rollers 22 which blocks 34 form retaining guides4 for the Y lower edge of the upper door section 18. The upper edge 37 of the lower'fdoor section 19 is doubled over and projects under the T-heads 35 of the guide blocks 34. Thus these T-head guide blocks form retaining guides for the upper edge of the lower door section 19.

The lower door section 19 is strengthened by having three transverse ribs 41 struck 4dica'ted by vtrial pivotalbolt or out from its surface, and an additional transverse rib 42 below these is similarly struck out. Across the lower part ot this door section 19 transverse Z-bars 43 and 44 are riveted, with their free anges opposed to oneanother to form retainingrruides for the auxiliary sliding doors 45. Ibach door .45 consists of a sheet of metal with its edge 46 turned' outwardly to give strength and with an angle bar 47 riveted along the edge toward the center of the main door. Each `auxiliary door normally closes an open ing in the main door section 19, these openings having in4turned edges 48. Further more, the edges adjacent to the center of nagainst-the auxiliary door openings when `they arein closed position.

Riveted at the center of the strengthening rib 42 is the bracket 52 which carries a cenrivet 53 on which the le ver 54 is tulcrumed.. At the lower end of this lever 54 is a handle 55 and a lockingv bar 56 is pivotally attached to the other end byl means of the rivet 57. This locking bar 56 is adapted to reciprocate in the guid clips 58, which are made wide enough to allow for necessary lateral movement of the bar 56. vOn the upper edgeof the door section'19 is a clip 59, and on the lower edge of the door section 18 is an opposedclip 60,.

these two clips registering when the doors are closed and being both engaged by the bar 56 when it locks them in closed position.

Pivotally attached to the lever 54 is the 'endvof the link 61, the other end @thereof being olset and connected by the pivot pin 63 tothe end of the crank arm 65 on the rotary shaft V64. This shaft 64 is rota- -tably mounted in brackets 66 and its ends are oi'set as indicated by the reference nuj merals 67. When in locked position, these oi'sets 67 -lie directly adjacent to the ends of the auxiliary doors 45, thus locking the latter in closed positions.

-. A heavy angle bar having one ange much wider than the other is provided for a door sill, the ange (Fig. 4) lying on the wooden sill 15 and the narrow liange 71 projecting upwardly to afford a track for the rollers v74. These rollers 74 are supported between' brackets 78 and the reinforcing plate 72 which extends across the lower edge of the lower door section 19. The lower edge of the main sheet metal plate 19 is offset as indicated by the reference numeral 68 and' its extreme edge is doubled as indicated by 69. The lower ends of the brackets 73 are hooked under, as indicated by 75, so as to keep the rollers 74 on theA track 71.` The angle bar 70-71 not only extends across the lower edge of the door opening, as shown in Fig. 4, but also extends otli' to the right, so as to afford a track for the rollers 74 when the door section 19 is opened to the right. This portion of the bar 70-71 at the right of the door opening has the flange 70 bent down, as indicated by 70', and bolted to the side wall 0f the car.

The hasp 77 on the staple 76 is adapted to lap over the lever 54 and have its tree end secured in place by the bolt 7 8 engaging the staple 79.

8,0 is a pivoted stop which hangs by gravity in a position to hold the bolt 78 in its place.

lt will be observed that when the parts have the relation shown in the drawings,

the upper door section is prevented from moving to the right because the edge 25 is pushed tightly under the lip 23. In a similar manner the lower door section 19 is prevented from moving to the lett. Moreover, the doors are locked together by means of the ybar 56 engaging the loops 59 and 60, andthus both door sections 18 and 19 are lfcked against movement in either direction. At the saine time that the door sections are locked together, as described, the auxiliary doors 45 are locked in closed position by the offsets 67.v Ot course the locking action that has just been described can be made secure against interference by sealing the hasp 77 to the staple 79 so as to prevent an'y movement of the lever 54. When it is desired to open the doors the hasp 77 must be released, and then by swinging the lever 54 to one side the auxiliary doors 45 will be released and at the same time the locking bar 56 Will be withdrawn from the clip 60. Then, if desired, the upper door section 18 can be moved aside to look into t-he car Without disturbing the lower door section 19. lf there is grain in the ca r the auxiliary doors 45 can be opened so as to permit it to run out and relieve the pressure against the door section 19 preparatory to opening the latter. The inverse operation of closing and locking 'the doors will be readily apparent. It will be observed that the top and bottom edges ot the door sections are restrained at all times from swinging out away from the car wall. The T- heads 85 restrain the bottom edge of the upper section 18 and the top edge of the lower section 19. The lateral edges of the door sections securely engage the coaeting strips or cleats fastened to the side posts, so that when the doors are closed, not` only are they held strongly against pressure from within, but there is a tight fit that prevents the escape of grain from within the car.

It will be seen from the foregoing specication that I have invented a door especially adapted to railway freight cars, which serves as an ordinary outside door, but is also adapted to retain grain in the car, thus at the' same time fulfilling the additional function of a grain door. It will be seen that I have provided secure means for holding this door against the pressure of the grain from within and that I have avoided possible cracks or gaps where grain might escape; also that I have provided secure means for locking the door sections in closed position.

I claim:

1. In a device of the class described, a door comprising upper and lower horizontally movable sections, the lower edge of the upper section being struck out and lapping past the upper edge of the lower section, a downwardly projecting plate attached along the lower edge of the-upper section above the said struck out portion, and T-heade attached to the side post of the door openings, said T-heads lying within the said struck out portion and engaging the said downwardly projecting plate and the top edge of lower door section.
